SPLASH-TROUGH FOR OILING SYSTEMS,

Specification of Letters Patent.

Patented Sept. 8, 1914.

Application filed September 3, 1913. Serlal No. 788,832.

, To all whom it may concern:

of a crank case such as is commonly employed on automobile or marme engines or motors, the construction being such as to provide an increased depth of oil at those. parts thereof from which oil is dipped or splashed up by a connecting rod of the, motor, when the latter is inclined in any dil rcction.

It is further desired to provide a splash; trough or auxiliary reservoir having the' above noted characteristics, which shall be relatively simple and inexpensive in construction and which may be conveniently applied to the crank case of the motor in any desired number depending upon the number of cranks, etc., which it is required to lubricate.

These objects and other advantageous ends I secure as hereinafter set forth, reference being bad to the accompanying drawings, in which:

Figure 1, is a transverse vertical section of an engine crank case showing my invention as applied thereto; Fig. 2, is a plan of the various parts shown in Fig. 1; and Figs. 3 and 4, are vertical sections taken respectively on the lines aa and bb, Fig. 2, further illustrating the construction of my invention.

In the above drawings, 1 represents the lower part of the crank case of an engine or motor such for example as is commonly used for the propulsion of motor vehicles or boats, and while such an engine may have any number of connecting roils 2 I have illustrated but two of these in the present instance. These rods are operatively connccted to the cranks on the main shaft 3 of the motor or engine, and each of them has at its lower end a downwardly projecting piece 4 constituting a finger or dipper for collecting and splashing up oil from an auxiliary reservoir 5 mounted in or forming an integral pa rt of the crank case structure 1. In the case illustrated there is one of these auxiliary reservoirs 5 for each of the connecting rods 2, and as shown, each reservoir is removably held to columns or brackets 6 projecting upwardly from the bottom of the crank case 1, by means of bolts 7. Each of the auxiliary reservoirs 5 is formed in the shape of a relatively shallow, substantially rectangular box or container elongated transversely of the crank case 1 and supported in such a position that when its co-acting connecting rod 2 is at the lowest portion of its stroke; its dipper 4: will extend below the surface of the oil contained in the said reservoir.

At the ends 8 or the auxiliary reservoir I provide level determining overflow openings 9 and 9 whose bottom edges are at the height at which it is desired to normally maintain the oil level and it is noted that said openings are formed in diametrically said openings are formed in diametrically oppositc parts to the two ends 8, preferably imreservoir. Adjacent the ends and along opposite sides of the auxiliary reservoir 5, I provide two L-shaped troughs 10 and 10, so designed that each of then: receives the oil flowing out of one of the ov-rflow openings 9 0r 9. The extremity of och trough 10 or 10 most distant from ile'op'ning 9 or E) is in turn provided with a level determin ing overflow opening ll or 11, the case may be, whose bottom edge is at substantially the same level as the bottom (41,195 of said overflow openings 9 and 9. With such an arrangement of parts, the oil entering one of the troughs at a point adjacent one side of the auxiliary reservoir 5,is coinlhcted along the opposite side thereof so as to be ultimately discharged at some point adjacent so id side. it being noted that each of the troughs holds a small quantity of oil. The length of tho side portion oi each trough is inmiatcrial so that it extends beyond the center of said auxiliary reservoir 5.

A pump driven from any suitable part of the engine or motor through a rod 13, has its intake connected through a screened inlet pipe 14 to the lower portion of the crank case 1 which forms a main reservoir receiving the overflow 1' mm the opcnings 11 and ll of the auxiliary rescwcirs; the discharge pipe 15 of the pump being connected to a distributing pipe UK to which are connected delivery pipes 17 discharging into the various auxiliary reservoirs.

Under operating conditions, each 'of the connecting rods 2 operates in a plane passing through the longitudinal axis of its auxiliary reservoir 5, and since the pum) continuously delivers oil to all of the auxiliary reservoirs, the latter are normally filled with oil to a constant level determined by the height of the bottom edges of the overflow openings 9 and 9. The dipper 4 on each rod therefore enters the oil in its reservoir at each revolution, and collects andsplashes up a certain quantity thereof so as to lubricate the parts of the engine or motor in a well known manner. The surplus oil not splashed up passes through the overflow. openings 9 and 9 into the troughs 10 and 10, from whence it flows through the overflow openings 11 and 11 back to the main reservoir formed by the crank case 1. If under conditions of operation the crank case should be laterally inclined, as for example, when the motor vehicle on which it is mounted hasits wheels on one side in a rut, the oil in each of the auxiliary reservoirs runs toward one end of the same, and while a portion of the oil in one of the troughs, 10 for example, is at once discharged into the main reservoir through its overflow opening 11, the oil in the other trough 10 flows to the end portion of the same and through the overflow opening 9 thereof is added to the oil body in the auxiliary reservoir thus raising its level. The overflow 11 now being higher than the level of oil in reservoir 5, no oil will flow through the troughs l0 or 10 until the pump has raised the oil level in said reservoir to a point from which it may overflow as above described. As a result the dipper 4 of the connecting rod at each revolution extends deeper into the oil and consequently splashes up a greater amount of the same, as is desirable under the conditions noted. Obviously, if the motor is transversely inclined in an opposite direction, the second trough 10 serves to cause an increased depth of oil as just explained. Again if the motor vehicle or boat on which the motor is mounted should be longitudinally inclined, there Would result a transverse inclination of all of the auxiliary reservoirs, and while as before the oil in One of the troughs as 10, for example, would shortly be discharged through its overflow opening 11, the greater part of the oil in the other trough 10 would collect in the end portion thereof and flow through its overflow opening 9 into the body of the reservoir. The overflow 9 now being higher than the level of oil in the reservoir 5 there is no flow of oil through overflow 11 until the pump has raised the level of nil in ,a d reservoir 5 to the level ofsaid overflow 11. As before, the dipper on the connecting rod would extend more deeply into the oil than under normal conditions so that lar e quantities would be splashed up to provide the additional lubrication required, when, for example, the vehicle was ascending a grade.

In any of the cases above noted the return of the motor to its normal level position is at once followed by the discharge of the surplus oil in the auxiliary reservoir into the two troughs 10 and 10 so that the connecting rod merely splashes up the predetermined quantity of oil from the body thereof in the reservoir wherein it is maintained at the desired depth as above indicated.
